Description

Technical field [0001] The present invention belongs to a semiconductor laser device. More specifically, the present invention relates to an assembling device for coupling multiple single-tube semiconductor lasers to a single-core optical fiber. Background technique [0002] The structural characteristics and light-emitting characteristics of semiconductor lasers determine that the light emitted by it has a larger divergence angle and a narrower light-emitting area in the direction perpendicular to the active layer (commonly known as the fast axis), and has a parallel active layer direction (commonly known as the slow axis). With a smaller divergence angle and a larger light-emitting area, coupling a semiconductor laser into an optical fiber has a wider use significance. There are many methods for coupling a single-tube semiconductor laser to an optical fiber, such as direct coupling, spherical lens coupling, aspheric lens coupling, and fast and slow axis collimation coupling.
